CA Computer Science

I think you can't pursue Computer Science because it is a Science stream course. You can go for CA if you are interested in accounting ormay go for IIM if you are interested in management or business studies.
On the other hand, IAS is most difficult but if you are interested in extensive study and are a seeker of knowledge, you may go for this.
So all of the courses totally depend on your field of interest.
Your percentage is good, so you can be admitted in a reliable course which you want to do.
However, universities have some other criteria, so it varies. All the best.

Hello Pooja,
BBA is just a degree. If your heart is not in that then you should go after your subject about which you are passionate. You can think of taking up a job too. There are plenty of careers in today's world. But you will succeed only if you are passionate about that subject or topic.
So, my advice is to follow your passion.
